MECHANICAL MOVEMENT.

T 0 all whom t may cof/tecra.'

Be it known that I, Vieron R. DnsrARD, a citizen of the United, States, residing at Hinsdale, in the county of Du Page and State of Illinois, have invented a certain new and useful Improvement in Mechanical Movements, of which the following is a full,

clear, concise, and exact description, reference being vhad to the accompanying drawings, forming a part of this specific-ation.

Iy invention relates to mechanical movements and has vfor its object the provision of improved actuatin means for such mechanical movements. y invention is applicable, of course, toa great variety of'devices and amongst others it finds particular use in connection with switch movements for electrical devices. y

In the application herein I show my invention as particularly applied to a socket for incandescent lamps o r plugs, it beingo-fcourse understood that the description of my invention in connectio-n with this specificv form thereof is not intended as a limitation. In the particular form herein chose-n for illustration I provide an electric switch movement of the quick make and break valriety which has a. lineally movable tension element adapted by succeeding movements in a given direction first to make the circuit and thento break it'. My invention. concerns itself particularly with means to actuate this tension element. The means which I prefer to employ are adapted for movement in a substantially universal manner and in the preferred form are also adapted for movement lineally.

l Iwill describe this particular form of my invention more in detail, in whichd l Fig'. 1 is a longitudinal sectional view of a switch movement having my improved actuating means;

Fig. 2 is a top view of a portion of the device shown in Fig. 1;

Fig. 3 is a sectional view on line 3 3 of Fig. 2, and

Fig. 4 is a view similar to that of Fig. 3 showing my actuating device in` one of its many actuating positions and showing the 50 switch movement in its alternative position. Referring more particularly to Fig. 1, I show a socket 10 within which a switch movement is mounted including the movable switch arms 11, 11. 'These movable switch arms 'are pivoted at 12 and are electrically Specification of Letters Patent.

tail piece 19 is shiftingly mounted in the upturned extremity 20 of the plate 16,' a spring 21 normally holding this plunger 18 to the right (Fig. A tension element 22 is secured to the forward end o-f the plate 16 and a` retra'ctile spring 23 restores this plate 16 through the abutments 24. Now when'- ever the tension element 22 is moved to the right, fromthe position shownin Fig. 3, then the plunger 18 engages the lower crossstrip of the bridge piece 13 thereby tendingto swing the rswitch element 11 in a contra-clockwise direction. This however is prevented by reason of the fact that the varms 15 rest upon the protruding sides `of the plate 16. During this movement of the plate 16 to the right the springs 21 and 23 are of course compressed and the plunger 18 and tail piece 2O are prevented from moving to the right. After a continued movement@ of the plate 16 to the-` right suicient to permit the arms 15 to register with the cut away portions 17 then the tendency on the part of the plunger 18 backed by the spring 2l to throw the switch element in a clockwise retract, due to the action of the spring 23 and the release of the pull upon the tension element 22, the parts move back into the position shown in Figs. 1, Q and 3, except that the switch element 11 is in the alternative position as shown in Fig. 4. Upon the next, forward movement of the plate 16 the plunger 18 would engage the upper cross piece of the bridge 13 and by a similar mode of 105 operation would move the switch element 11 back to its starting position, as shown 1n Figs. 1, 2 and 3.

My invention concerns itself particularly with means for actuating this tension ele- 11g)y ment 22 and the vmeans which I employ consist of an actuating member 25. -This actuating member engages the tension member 22 through the agency of the head 26 provided upon, this tension member. This head is loosely seated against the shelf 27 provided in this actuating member. Projecting toward the left from this shelf portion is the ,hood or petticoat 28 which normally abuts the stationary plate 29, upon which vall of the actuating parts of the switch are mounted. The actuating member is likewise provided with a forwardly extending hole 30 extending forwardly from the shelf portion 27. It will be seen that in whichever direction this actuating member is moved angularly, using any portion of the periphery of the head 28 as a fulcrum, serves to pull the tension member 22 to the right. The actu-- ating membermay be tilted in any direction, as of course readily apparent so that it occupies any conceivable angular position upon this actuating member 25, even thoughI the pull were not exactly in a straight line would yet pull the tension member 22 to the right, even though the actuating member were tilted slightly. -In the normal condition of operation, however, it is assumed that there will not be direct pull as often as there would be a use of this actuating device 25 in the manner shown in Fig. 4, wherein the pcriphery of the hood portion 28 isV used as a fulcrum. Itwill likewise be seen that this actuating member 25 may, if desired, have aA pull chain 3l attached and the tension member 22 will be actuated whatever may be the direction of pull exerted upon the actuating device 25 by the chain 31. This chain may desirably beheld in place by having one of its balls confined within theu fingers 32 of the split catch 33, the particular form herein contemplating that the ball. is inserted between the finger pieces 32 before the catch 33 is inserted in place in the actuating device 25. This catch 33 by reason of its split character permits the fingers 32 to be separated 'for the purpose of introducing the ball of the chain 3l. I likewise prefer to insert a plug of insulation 34 between the head 26 and any part metallically lconnected with the chain so that there isl an absolute insulating v effect between any part of the chain and any part of the switch movement. Of course, any

other suitable means other than the plug 34 would accomplish this same result. The universal nature of my actuating device will thus be readily clear.

A movement of the actuating device 25 vof the structure herein shown into any position other than Vthe normal position causes .an actuation of the switch movement. rThe actuating element is universally movable, using any part of its inner hood as a fulcrum, and

the combination of a snap-action'switch having cooperating switch elements, and a lever universally operable for effecting such action of they switch elements.
